The outer ring of drawn cup needle roller bearing is punched with the high-quality steel sheet. The outer ring has thin wall.The drawn cup needle roller bearing has the characterstics of small radial section area, large load carring capacity ,less inertia and economic manufacture. It is suitable for small section heght, or when the housing bore isnot used for raceway , this type is recommended to use .The bearing is assembled into the housing bore under a certain pressure without fu rther axial location.

The draw up needle roller bearing generally takes its shaft diameter as the internal raceway .However , the proper LR type inner ring can be used in accordance with application condition.

Our Advantages:

1. Provide full range of standard bearings.

2.Look into and develop various non-standard bearing according to customers’ special needs.

ABEC is almost meaningless for skates or boards. It is an industrial standard for VIBRATION (not speed) in bearings on high speed machines that run at speeds that would be over 200 mph on a board. It became important because the previous ones that were used (20 years ago) were a grade called precision which are really sloppy. You can actually see them move them if you twist the center to the side. ABEC bearings were a huge move up and came without the heavy grease the was needed to make the precision bearings not rattle like maracas. However, now that a number was involved, the marketing people get into the idea that they can advertise higher numbers because people assume that higher is better. Almost all the difference in how fast a bearing rolls is in what lubricant is used.

Q:how much should it cost to replace all the bearings in my 300ex?

Q:What is the bearing capacity of needle bearing and copper sleeve?

What do you mean?Needle roller bearings or rolling friction, copper sleeve is a sliding friction, copper is a set of friction is normalAs for other forces, I don't know what the difference is

Q:What are the fastest longboard bearings?

well okorder.com and pretty much the more you are willing to spend the better they will be. buy some speed lube and youtube how to clean bearings.. they will be smooth as ever.

Q:Can 3m General Purpose Adhesive Cleaner be used to soak long board bearings?

Q:Bones Reds Longboard Bearings!?

Free spin doesn't mean anything. You don't need new bearings unless yours are broken or rusted/seized. They won't make any difference. My Bones Reds spin for about 5 seconds.

608 STANDARD The most common bearing size is the “608.” Characterized by an 8mm core, a 22mm outer diameter and a 7mm width, these bearings are the industry standard and match up with nearly every skate wheel out there. There are also mini-bearings that can be used with the standard 608 bearing hub, but they require a sleeve to make them compatible.
